# DROP OPERATOR

## Name

DROP OPERATOR -- remove an operator

## Synopsis

    DROP OPERATOR [ IF EXISTS ] name ( { lefttype | NONE } , { righttype | NONE } ) [ CASCADE | RESTRICT ]

## Description

`DROP OPERATOR` drops an existing operator from the database system. To execute this command you must be the owner of the operator.

## Parameters

`IF EXISTS`

  Do not throw an error if the operator does not exist. A notice is issued in this case.

`name`

  The name (optionally schema-qualified) of an existing operator.

`lefttype`

  The data type of the operator's left operand; write `NONE` if the operator has no left operand.

`righttype`

  The data type of the operator's right operand; write `NONE` if the operator has no right operand.

`CASCADE`

  Automatically drop objects that depend on the operator.

`RESTRICT`

  Refuse to drop the operator if any objects depend on it. This is the default.

## Examples

Remove the power operator `a^b` for type `integer`:

    DROP OPERATOR ^ (integer, integer);

Remove the left unary bitwise complement operator `~b` for type `bit`:

    DROP OPERATOR ~ (none, bit);

Remove the right unary factorial operator `x!` for type `bigint`:

    DROP OPERATOR ! (bigint, none);

## Compatibility

There is no `DROP OPERATOR` statement in the SQL standard.
